FIGURES 6–9 in Character correlation and its use for identification

FIGURES 6–9. Dichotomous cladogram, ordered correlations, and output. 6, dichotomous cladogram that results in zero correlation between characters 0 and 1; 7, one correlation graph showing the maximal possible correlation between two additive characters; 8, correlation with incomplete ordering; 9, output to determine which state-combinations are compatible only with state 1 of the third character (combinations that predict only 2:1 in bold).
